Resolve "Build/Pipeline/Environment List Inconsistency Row Height"

#### What does this MR do?
* Changes generic table class from `builds` to `ci-table`. It was getting confusing using `builds` for `builds`, `pipelines`, `environments`
* Sets height on builds rows for continuity

#### Are there points in the code the reviewer needs to double check?
Apparently you can't set `min-height` on any `table` elements but you _can_ set `height`. For some reason, even if the content within happens to start wrapping, the row height will grow instead of letting the content overlap. Which is a good thing. Just kind of weird.

#### Why was this MR needed?
Different row heights on builds depending on content
